Answer:

The 4th option. "Sarah rounded $6.95 and 9.5 down. Her estimate of $54 is too low."

Explanation:

Well, if you check Sara's math during option 4, you will find that when you round 6.95 and 9.5 down, you get 6 and 9.


6 * 9 = 54

If she would have done it correctly, she would have gotten "66. 025"

Therefore, 54 dollars is too low.
